Abstract

1368048 Electromagnetic clutch GENERAL MOTORS CORP 15 March 1973 [20 March 1972] 12424/73 Heading F2C An electromagnetically actuated coil spring clutch for driving an output shaft 14 (to a compressor) from a pulley assembly 63 comprises a stationary electromagnetic coil 46 and a coil spring 77 engaging a slot of an armature ring 86 at one end, surrounding a hub 64 of the pulley assembly and attached to a driven hub 34 at its other end, so that on energization of the coil 46 the armature ring 86 frictionally engages a wall 68 of the pulley assembly 63 on either side of arcuate slots 73 due to the flux following path 104, which causes the spring 77 to be wound up to engage hub 64 and so transmit drive therefrom to shaft 14 via hub 34. In an alternative embodiment a resilient element between the hub to which the spring 77 is attached and shaft 14 absorbs shocks, and the flux follows a different path travelling radially out into the pulley assembly rather than axially across a gap 72 as shown.
